title: Release of colicin E2 from Escherichia coli.
abstract: Treatment of Escherichia coli K-12(ColE2.P9) with 500 ng of mitomycin C per ml resulted in rapid and almost synchronous colicin E2 production. Colicin accumulated outside the cytoplasmic membrane, most probably in the periplasmic space. Colicin release occurred during a period in which the turbidity of the culture declined markedly. Periplasmic alkaline phosphatase was released during the same period, but cytoplasmic beta-galactosidase release was delayed.
